in eillciency and servlceability. The inventioncontemplates the use of either entire manual or like operation, or partial or main operation through the use of suitable power or pressuremedium, preferably utilizing, in the lattercase. convenient and suitable source of power or energy availablein connection with the functioning of the vehicle.

With the above and other objects in view, the invention consists in the novel and useful pro-v vision, formation, construction, combination, association and interrelation ofparts, members and features all as hereinafter described, shown in the drawings, and finally pointed out in claims.

In the drawings, in which like parts are designated by similar reference characters:

Fig. 1 is a partial perspective and outer view of an automobile, the front door member having double walls, both of which are shown broken away to disclose the operating mechanism;

Fig. 2 is a view upon an enlarged scale showing operating means, the same being observed from a direction inwardly of the car, the inner wall of the double front door being removed to disclose the mechanism;

Fig. 3 is a vertical sectional view taken upon the line 3-3 Fig. 2, and looking in the direction of the appended arrows, the window being shown in raised and locked position;

Fig. 4 is a similar view, looking in the same direction. the window being shown in lowered and locked position;

Fig. 5 is an enlarged fragmentary view of parts shown and as-viewed in Figs. 2 and 4, showing particularly the operating and locking means in their association, partly broken away:

Fig. 8 is a sectional view taken upon the line- 8-4, Fig. 5, and looking in the direction of the appended arrows;

Fig. 7 is a view similar to Fig. 2, but illustrating the use of pressure produced in the functioning of the vehicle as means for actuating the operating means, under manual control, the window being shown in raised and locked position;

Fig-8 is a view similar to Fig. 7, showing, however, the window being lowered and in unlocked condition; Fig. 9' is an enlarged fragmentary sectional view of part of the door structure of the vehicle with a hinge thereof, showing the door in closed position for the utilization of pressure in accordance with the showing in Figs. 7 and 8, with the line open so that negative pressure, as from partial vacuum in the car installation, can permit atmospheric pressure to actuate the windowoperating means; and

Fig. 10 is a view similar to Fig. 9 showing the door partly open and the line to the negative pressure source closed.

Referring with particularity to-the drawings, I have shown partially the exterior of an automobile, in'Fig. 1. with a forward door A with its window a, and the usual side running board b and vehicle top 0. The window a is shown as a vertically slidable panel operating at its edge or inner ends as at ll between spaced plates i9 and 2! which are bolted together, on a flange 2| upon the plate II, and in turn bolted to the inner door wall structure, as at 26, and accommodating between them the pivotal play of said toggle arms N and I]. These toggle arms are in turn connected with a slidable housing I including spaced side plates 22 and 23, by means of link arms 24 and 28, in turn pivotally connected with the toggle arms I 4 and I5 each at one end as at 21, and with and between the spaced plates 23 and 24 asat 2!, said slidable housing embracing and adapted to move lengthwise of a vertical bar 20 which is bolted or otherwise secured at its upper end, as at 30, to and between the lower portions of the plates l9 and 20. The slidable housing I s urged in a direction to cause the raising or closing of the window by coiled compression spring Illa which surrounds the elongated bar 2! bearing at the lower end upon an adjustable collar II which may be piurally positioned with respect to adjustment and so held by pin "adapted to be positioned in one of a plurality of openings 33 in the bar 2!; and bearing at its upper end similarly against a collar 34 at the lower end portion of the housing f. The spring 3. acts as a counterpoise for the weight of the window a and attached parts, the potential energy stored therein upon lowering of the window becoming kinetic upon the raising thereof. The lower end of the her it is also secured to a bracket 35, mounted between the inner and outer walls d and e of the door, as at 36 directions to cause respectively the raising and the lowering of the window, by and through a locking member g which is pivotally connected Ihe slida-ble housing I is operated in opposite is pivotally received, by pin Ma, .2. link arm. 62,

pivotally connected at its lower end portion, as at it, with a lever arm 44 pivoted at to in a supporting bracket 48 between the door walls, and with which is fixedly connected an operating lever El ranging generally upwardly, for swinging of the lever arm 44 to move the link is and rock and then actuate the locking member 9. 3

This latter actuation, in the pivotal swing of the locking member a, serves to first unlock and then look the locking member with respect to the slidable housing in connection with which it is plvotally mounted by means of the detents M. The locking member has a transverse locking pin 48 sng the space between the space 51, disposed within a cylinder 58. This cylinder has ports 58 and 60 at its upper and lower ends respectively, with which communicate pipes ti and t2 leading to opposed sides .of a valve housing 69 within which is mounted a. rotating fourway valve t l controlling opposed ports 65 and '0 respectively communicating with the pipe 6i and 82, and likewise controlling opposed ports 81 and 68 each of which is approximately 90 degrees from both of the ports-86 and to. The valve 64 is mounted upon a shaft 89, provided outside of the housing 68 with a lever arm to, which in turn is connected by a link arm it with a crank arm l2 similar to the lever or cranh'a'rm M in the other figures, and similarly provided with an operating lover or arm 73, whereby the valve may be thrown. The port 68 communicates with a pipe it mounted, together with the M 18 lust recited, in connection with the door and between the walls thereof, (save and except the operating lever iii), and whichextends to and is coupled with a nipple iii'adapted to be engaged with the tubular terminal portion 16 of a poppet valve ll, the tubular portion of which is slidabiy mounted within a fitting 58a secured to the body of the car'ioetween the walls 12 and e thereof, as at 80, such slidable part having ports ti which are closed when the door is open, but which are open within the chamber lfib of the fitting its so that said chamber may communicate through said tubular portion it with the nipple 1i and the pipe it. The poppet valve ii is normally urged to closed position by a compression spring .82 between it and one wall of the fitting. A pipe 83 is coupled to th fitting to communicate with a port 85 therein so that continuous communication may behad between the pipe "M and the plates 35 and Al of the slidable housing I and accommodated in slots 4! in the plates 22 and as or the slidable housing 1, in its play to enter one of a plurality of notches il in the adjacent side of the fixed bar 28, to loci: the housing 7 against further movement along said her. such cross pin 48 is mounted forward oi the inner end of a bolt Bi which is slidably mounted through an enlarged opening in the web 4|, and fined at one end to the plates 22 and 23 01 the member 1; and to urge into locking position the locking member a, there is a coil compression spring M bearing against a collar it surrounding the bolt 5! and in turn bearing against the web I. When the operating lever 41 is thrown in a suitable direction, the locking member 9' is swung or tilted to. retract the locking pin 68 tram the notch in which it is stationed in looking relation, such relation being shownin P18. 2, the

swinging in one direotiontaking place as shown low pressure or. vacuum side oi a line utilized in operating the vehicle. When the valve 64 is so positioned that the port 66 is open, with the door closed, the ports 65 and tit will be open, the ports 81 will be open to the outer air and the other port 65 or 68 will open to port 68.

Due to a given valve 64 position, either the port 59 or the port 60 will communicate through the housing to with the low pressure line I4. and

in Fig. 5, having a detent M, there being two at the ends oi the web ll, in a notch 55 or 5%,

in the slidable he 7, the latterbeing moved lengthwise oi the fixed bar 29, in one direction or the other, as-in a window opening directionas shown in Figs. it and 8, through the agency oi the pin 8?. n the window has been par- 7 tially or wholly opened or'closed, and the lever is released, the locking member a will swing so that the transverse locking pin it enters one of the notches 58 and the window is maintained in either partial or whollyopened or closed position, both detents 54 being in their notches.

' In Figs. 7, 8, 9 and 10, the link 42 is shown as replaced by a piston rod 42a having a piston the other port will receive atmospheric pressure to move the piston one way or the other tor raising or lowering the window as aforesaid. Spaced adjustable stops 8! and 86 are mounted upon a lever arm 81 mounted to play through'an eveor opening ins guide arm 88 fixed to the piston rod 42s a at 80, whereby, when the piston has execu a suflicient window-opening or window-closing travel, or just before such accomplishment, one of the stops will be acted upon to throw the valve arm 10, with which one end of the lever B! is connected as at 89.

into position to close the open air ports 61 and fifl terminating piston movement and the conseou'ent movement of the locking member'y and attendantparts- The general operetion oi' parts and featuresis as such description proceeded.

A feature of particular importance .in the invention is theprovision of the two toggle arms it and i5 and the two link arms 24 andv 25 respectively connected-therewith which impart an uniform uplift or downhaul at opposite sides of-the central portion of the window, the window actuating partsbeing disposed as shown, preferably, in such intermediate position that the actuation is thus unii'orm at both sides. This prevents Jamming or clogging oi the window and facilitates an easy window movement.
